Hi,
 
maybe, codes is our language :-)
 
% define a new head
\definehead[backmatterchapter][chapter]

[”­]
 
The chapter title "Backmatter" in the backmatter won't appear in the Contents. Why? How can I make it appear in the Contents? 

You have to redefine the \completecontent command to include ”°backmatterchapter”± in the list of headings.

\definecombinedlist[content][part,chapter,backmatterchapter,section,subsection,subsubsection,subsubsubsection]
